• Invalid data found when processing input on ffmpeg m4s to mp4 transfer

  1er mars 2020, par keith scott

  The result of the power shell window

  I saw a post on here about converting m4s to mp4 and I have followed the steps of concatenating all the files into another m4s file that I called all.m4s and when I use the command ffmpeg -i allm4s.m4s -c copy video.mp4. I made the combined m4s file by coding an exe to add all the m4s files that have the word video in them to the m4s file. Here is the source code written in c# if you compile the code then that is the code I have used to make the m4s

  using System;
  
  using System.Collections.Generic;
  
  using System.Linq;
  
  using System.Text;
  
  using System.Threading.Tasks;
  
  using System.IO;
  
  
  
  namespace files
  
  {
  
      class Program
  
      {
  
          static void Main(string[] args)
  
          {
  
              string dir = Directory.GetCurrentDirectory();
  
              string[] info = Directory.GetFiles(dir);
  
              Console.WriteLine(dir + "\\allm4s.m4s");
  
              Console.ReadKey();
  
              foreach (string name in info)
  
              {
  
                  if (Path.GetFileName(name).Contains(".m4s") && Path.GetFileName(name).Contains("video"))
  
                  {
  
                      using (Stream srcStream = File.OpenRead(name))
  
                      {
  
                          using (Stream destStream = File.OpenWrite(dir+"\\allm4s.m4s"))
  
                          {
  
                              srcStream.CopyTo(destStream);
  
                              Console.WriteLine(destStream+name);
  
                          }
  
                      }
  
                  }
  
              }
  
              Console.ReadKey();
  
          }
  
      }
  
  }

  I think if there is to be an issue it is to do with this allm4s.m4s file as the file size is about 1.5mb even though each segment m4s is about 750kb each and there are quite a lot.If anyone has a way of adding concatenating lots of files together through a program/application that would be useful.

• How to fix the "No working C compiler found." problem for compiling x264 in Linux ?

  27 février 2023, par gc xu

  Firstly I have read all other solutions related to this problem, including adding path and reinstall yasm, nasm, gcc...
I git clone the source code from https://code.videolan.org/videolan/x264.git.
Then, I run command ./configure, it shows

  


  ./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
./configure: line 169: conftest.log: Invalid argument
No working C compiler found.


  


  I check the file "config.log". It shows :

  Plus I wonder is there something to do with nasm ? Becasuse I install nasm with some C grammer problems :

      |                ^~~~~~~~

  I have read all other solutions related to this problem, including adding path and reinstall yasm, nasm, gcc...
I want to install x264 to configure it in ffmpeg. Thanks for all your answers !
